The use of the CrO_2-terminated interface instead of TiO_2 may significantly enhance magnetoelectricity in the system, showing an unexpected change in magnetization induced by the electric polarization reversal. In the case of L=2, for instance, the magnetic order of the Fe bilayer can be switched from nearly zero ferrimagnetic to ferromagnetic upon polarization reversal.","authors_text":"Ingrid Mertig, Martin H\\\"olzer, Michael Fechner, Sergey Ostanin","cross_cats":["physics.comp-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2010-05-18T08:57:55Z","title":"Effect of interfacial Cr on magnetoelectricity of Fe2/CrO2/BaTiO3(001)"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1005.3122","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:cecc0d12e8ec71f46c49f118b99b9740106ede15d5c5f1f70cc00a4775f3692c","target":"record","created_at":"2026-05-18T02:07:17Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"04115b43fbb344174536681c1359ee78108dec2e218eb3b8deb4a196b4e99c3f","cross_cats_sorted":["physics.comp-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2010-05-18T08:57:55Z","title_canon_sha256":"aac16210201fe0041d17c82332a5b3cf24ce5280d606c7f91dd9a057fb5b743a"},"schema_version":"1.0","source":{"id":"1005.3122","kind":"arxiv","version":1}},"canonical_sha256":"50880e0e8040d95c74206efb177e6413afbc59a214ed56e1a59d70e583f69452","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"50880e0e8040d95c74206efb177e6413afbc59a214ed56e1a59d70e583f69452","first_computed_at":"2026-05-18T02:07:17.725702Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:07:17.725702Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1v2JMjd5VnBW05kSlGNb+BgMCV0mFyJW5YqQ7DyPi1t5RKlQOltyTdkYtPVm33hF/wqfVyLhMuTwU9XpHFP1DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:07:17.726370Z","signed_message":"canonical_sha256_bytes"},"source_id":"1005.3122","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:cecc0d12e8ec71f46c49f118b99b9740106ede15d5c5f1f70cc00a4775f3692c","sha256:3e164d852610971a9c466a477b7f7c7a309d507268d25bc0c0a49a1f3fd2bcde"],"state_sha256":"e8504d57e3f34f961f55b5ff6d747760978693afb0bd760461d580157b2903f6"}
